[Buildroot] [git commit branch/2021.05.x] support/testing: test_openrc: switch to ARM arm toolchain and builtin kernel

[Peter Korsgaard <peter@korsgaard.com>]

commit: https://git.buildroot.net/buildroot/commit/?id=9420af6c55f25cf2dd6f0860450269a7bedeca3f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.05.x

The kernel 5.5.7 curently used by the test doesn't build with host
gcc >= 10 due the gcc default -fno-common. See GCC 10 porting guide [1].

/usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x20): multiple definition of `yylloc'; scripts/dtc/dtc-lexer.lex.o:(.bss+0x0): first defined here

But we can't just update this test to the next linux kernel LTS 5.10.y since
the minimum gcc version has been updated to gcc 4.9 since 5.8 kernel [2]
and the Sourcery CodeBench ARM 2014.05 is used (gcc 4.8 based).

Enable arm cortex A9 and VFP support to switch to the ARM arm prebuilt
toolchain (the Bootlin toolchain could be used).
While at it use the prebuilt buildin kernel for the vexpress target
recently updated to 5.10.7.
